First, you really need to increase the heap size. You have 16GB so take advantage of it. Then Concurrent Mark Sweep may actually work.
You didn't mention what JVM you are using, it matters. I did a presentation recently on Java GC that you might be interested, http://docs.google.com/Presentation?id=dfzxvg3f_14hrjpfn . If you have any more questions feel free to contact me offline as this is probably off topic.
